Abstract [en]

This report is based on a case study at Jensen Sweden and aims to shorten lead times in their production system. Some of the problems are recurring material shortages and that the production planning is driven by a subjective management. The stocking density in the production is uneven and different departments are resource efficient without any focus on the product flow as a whole.The above problems cause multitasking that has a number of negative effects and in addition generate a lot of work in progress. The effect will be long lead times which complicate the discovery of manufacturing deviations.The solutions presented in this report are aimed at breaking down the tact of the incoming production activities, further a structure on how to control the daily management is suggested. Using a Gantt-chart, the stocking density in production relative to the capacity is visualized. The Ganttchart also visualizes the critical chain. Flexible teams are introduced in order to balance the capacity and occupancy between the stations. An important parameter to decrease the complexity of the system is to minimize the number of orders in production. The company is working with customer-specific projects and the intention of the methods used in the report is that they should be to be applicable to companies with similar production processes.
